Description

Technical Field

[0001] This utility model relates to the field of toy technology, and more particularly to a torso twisting drive device for an animal toy. Background Technology

[0002] Animal toys on the market are diverse. For example, the interactive intelligent animal toy disclosed in application number CN201620792287.0, by driving motors in various moving parts to change the relative angles of these parts, can simulate various actions of natural organisms, such as turning, flipping, curling up, and pouncing. Compared to existing interactive intelligent toy animals, this intelligent interactive toy expands the degrees of freedom of its parts, enabling more complex and realistic movements. Although the torso of this animal toy includes pivotally connected forequarter and hindquarter sections, these sections cannot rotate autonomously, thus limiting the expansion of the torso's degrees of freedom and resulting in poor practicality.

[0026] Please refer to the following at the same time Figure 1-4 This embodiment provides a torso twisting drive device for an animal toy, including a housing 1, a motor 2 fixed on the housing 1, a gear set 3 driven to rotate by the motor 2, and an angle control group 4 for detecting the rotation angle of the output end of the gear set 3. It can be understood that the housing 1 has an inner cavity 10 and a first outer cavity 20 and a second outer cavity 30 respectively connected to the inner cavity 10. A first angle gear of the gear set 3 and the angle control group 4 is rotatably connected in the inner cavity 10. The motor 2 is fixedly connected in the second outer cavity 20, and a second angle gear of the angle control group 4 is fixedly connected in the second outer cavity 30. An angle positioner of the angle control group 4 is fixedly connected to the outer wall of the second outer cavity 30.

[0027] Specifically, housing 1 includes a first housing 11, a second housing 12, and a third housing 13. The first housing 11 and the second housing 12 are fixedly joined together by a threaded fastening structure to define an inner cavity 10. The second housing 12 has a motor slot 121 to form a first outer cavity 20. The third housing 13 and the second housing 12 are fixedly joined together by a threaded fastening structure to define a second outer cavity 30. It can be understood that the third housing 13 has two oppositely arranged latching rods 131, and an angle positioner of the angle control group 4 is fixedly fastened within the two latching rods 131. Further, the third housing 13 also has two oppositely arranged latching holes 132, which engage with the angle positioner to further fix the angle positioner to the third housing 13. In this embodiment, housing 1 also includes a fourth housing 14, which is fixedly connected to the outside of the motor slot 121 by a threaded fastening structure to close the motor slot 121. The fourth housing 14 has a mounting hole 141, the shape of which matches the shape of the end of the motor 2, and the end of the motor 2 is fixed inside the mounting hole 141 so that the motor 2 can be firmly fixed in the motor slot 121. It is understood that the fourth housing 14 also has a positioning sleeve 142, in which the shaft of the gear set 3 is movably inserted, making the connection of the shaft on the housing 1 more stable, reducing the vibration amplitude of the shaft, and playing a role in noise reduction and increasing the transmission efficiency of the shaft. Of course, in other embodiments, the fourth housing 14 may not be fixed to the outside of the motor slot 121, and the positioning sleeve 142 may not be provided on the fourth housing 14.

[0028] Motor 2 is electrically connected to an external controller, which is electrically connected to the angle positioner of the angle control group 4. When the angle positioner detects that the rotation angle of the output end of the gear group 3 is the same as the preset angle, the controller controls the motor 2 to stop working or rotate in the reverse direction. This allows the drive device in this embodiment to control the torso's twisting angle through the angle control group 4, so that the left and right twisting angles can be controlled within 45 degrees to ensure the realism of the torso twisting action and increase its visual appeal and interest.

[0029] The gear set 3 includes a first gear 31 fixed on the output shaft of the motor 2, a second gear 32 coaxially fixed to the external torso, and a transmission gear set 33 that drives the first gear 31 and the second gear 32. In this embodiment, the transmission gear set 33 includes a first transmission gear 331, a second transmission gear 332, and a third transmission gear 333 that are sequentially meshed. The first transmission gear 331 meshes with the first gear 31, and the third transmission gear 333 meshes with the second gear 32. Meanwhile, a clutch structure is provided between the two gears of the third transmission gear 333. The clutch structure includes an internal gear ring 3331 recessed on one of the gears of the third transmission gear 333, and an elastic movable strip 3332 protruding on the other gear of the third transmission gear 333. The elastic movable strip 3332 has tooth blocks that match the tooth grooves of the internal gear ring 3331, and the elastic movable strip 3332 can be meshed with the internal gear ring 3331 through the tooth blocks. The clutch structure on the third transmission gear 333 enables the gear set 3 to have an overload protection function. That is, when the output end of the gear set 3 (i.e., the second gear 32) is unable to rotate, the elastic movement of the elastic movable bar 3332 allows the two gears of the third transmission gear 333 to rotate relative to each other, thereby preventing the motor 2 from jamming and burning out. Of course, in other embodiments, the transmission gear set 33 can be composed of other numbers of gears meshing sequentially, and the clutch structure may not be provided on the third transmission gear 333.

[0030] It is understood that the transmission ratio between the transmission gear set 33 and the first gear 31 and the second gear 32 is in the range of 185-200. In this embodiment, the transmission ratio is 189. Of course, in other embodiments, the transmission ratio can be adjusted to other values ​​such as 185, 190, 195, 200, etc., to achieve deceleration and output power.

[0031] The angle control assembly 4 includes an angle positioner 41 fixed to the third housing 13, a first angle gear 42 coaxially fixed to the second gear 32, and a second angle gear 43 fixedly connected to the central rotor 411 of the angle positioner 41. The angle positioner 41 also has a locking foot 412, which engages with a locking hole 132. The first angle gear 42 and the second angle gear 43 are meshed together with a transmission ratio of 1. In this embodiment, the first angle gear 42 has a wide tooth groove 421 on its gear surface, with a tooth width greater than other tooth grooves. Correspondingly, the second angle gear 43 has a wide tooth 431 on its gear surface that engages with the wide tooth groove 421. The engagement between the wide tooth 431 and the wide tooth groove 421 prevents the first angle gear 42 and the second angle gear 43 from disengaging and vibrating, ensuring the accuracy of the angle positioner 41 in detecting the angle. In other embodiments, the wide tooth groove 421 and the wide tooth 431 may not be present between the first angle gear 42 and the second angle gear 43.

[0032] It is understood that the second gear 32 and the first angle gear 42 have the same axis shape and are both polygonal (quadrilateral in this embodiment). The second gear 32 and the first angle gear 42 are connected by a rotating shaft 34, which is movably fitted inside the positioning sleeve 142 and fixedly connected to the outer torso. The second angle gear 43 is coaxially fixed to the central rotor 412 through a rotating shaft 432. When the second angle gear 43 rotates with the first angle gear 42, the rotating shaft 432 can drive the central rotor 412 to rotate, so that the angle positioner 41 can detect the rotation angle of the rotating shaft 432 in real time and transmit the angle information to the controller. When the angle information received by the controller is the same as the preset angle, the controller controls the motor 1 to stop working or rotate in the opposite direction.

[0033] For clarity, certain features described in individual embodiments of the present invention may be used in combination in a single embodiment. Furthermore, various features of the present invention described in individual embodiments may also be used individually or in any suitable form in sub-combinations.
